Part of this is because problems (X) are complicated and people just as commonly demand the "simplest possible example" (Y) that demonstrates the problem. So people ask how to do Y, and then others ask why on earth they would do that.

One common example I've run into lately, as I've been reading about state machines, is people asking how to implement a simple react component as a state machine, and others objecting to the premise of the question since using a state machine for a simple react component is obviously a bad idea.
